I am about to have a contractor spray polyurethane foam into my house and he has given me a choice between PolarFoam 7300 regular and PolarFoam 7300 soya. I am having difficulty deciding. My contractor prefers the regular stuff because it is easier to work with and has better coverage and therefore will price the job a little cheaper. On the other hand the soya based product has a GreenGuard certification.

As I understand it the difference between the two is in the blowing agent. The SOYA is zero ODS (ozone depleting substance) and has no HFC (hydro flouro carbons???). As far as health to the homeowner there is absolutely no difference. They both contain recycled products. The PF-7300 has a slightly higher Rvalue of 6.9 v 6.0 for the SOYA. Soya more environmentally friendly. All foam starting in 2010 will be SOYA or the type of blowing agent used by the soya due to government ruling.

Any comment to help me decide? Thanks in advance.
